3. Basic Functions

3.1 VISCA Commands

Camera control is performed by VISCA Commands.

Timing Chart

As VISCA Command processing can only be carried out one time in a Vertical cycle, it
takes the maximum 1V cycle time for an ACK/Completion to be returned. If the
Command ACK/Completion communication time is shorter than the 1V cycle time,
then every 1V cycle can receive a Command.
VISCA commands are described in detail at Chapter 4 Command List.

Turn On a MP3010M-EV (from no power supplied)

When MP3010M-EV is turned on from no power supplied, MP3010M-EV transmits a
"Network Change" command through TxD. Because of "From No Power Supplied",
there might be invalid data transmitted before the "Network Change" command at the
time. One terminator "FF" is added just before the "Network Change" command, so the
terminator "FF" and other previous data and packets can be detected and must be
ignored.
